Start by preheating your oven to 400°F (200°C). This ensures that your chicken will cook evenly and thoroughly.

While the oven heats, take your chicken breasts and gently pound them to an even thickness. This helps the chicken cook uniformly, preventing some parts from drying out.

In a bowl, mix together the coarse kosher salt, smoked paprika, black pepper, granulated garlic, and onion powder if you’re using it. Rub this seasoning mix all over the chicken breasts. Add the melted butter or olive oil next, making sure each piece is nicely coated.

Lay the seasoned chicken breasts on a baking sheet. It’s best to keep them spaced apart, allowing hot air to circulate around each piece. This step will help achieve that perfect golden brown finish.

Slide your baking sheet into the preheated oven and set a timer for 25-30 minutes. Depending on the size of your chicken breasts, you may need more or less time.

Use a meat thermometer to check that the internal temperature has reached 165°F (74°C). This temperature ensures the chicken is safe to eat and remains juicy.

Once cooked, take the chicken out of the oven and let it rest for about five minutes. This allows the juices to redistribute, making each slice flavorful and moist.
